abstract

Nano-level 3-D measurement is one of the key technologies for the current and future generation of production systems for semi-conductors, LCDs and nano-devices. To meet with these applications, wide range nano-level 3-D shape measurement method using combination of RGB laser lights has been developed. It measures the height of nano-objects from the combination of RGB LED lights interference. To analyze the combination of RGB lights, the color analysis method on xy-color plane has been introduced. In this method, the color changes on xy-color plane means the height changes. Experimental system to measure the three micro-meter height has been developed, and succeeded to measure the 50 nm step and 1000 nm step samples. The method has been applied to measure a nano-device, a contact needle for measurement. The shape of the needle has been extracted, successfully.
